Combining EMA Crossover Momentum with Bollinger Band Mean Reversion

Summary

This strategy offers two independently switchable signal modules. Its momentum module enters long or short on crossovers between a 50-period and 400-period EMA. Its mean-reversion module uses 20-period Bollinger Bands with a two-standard-deviation width: the source buys when price crosses back above the lower band and sells when it crosses back below the upper band. The accompanying explanation presents the modules as approaches for different market conditions, while warning that both indicators can lag and band breaks can be unreliable during volatile moves.

The published backtest settings specify BTC/USDT Binance futures on one-hour bars from December 2024 to January 2025, despite the overview describing a five-minute timeframe. No returns, trade counts, or other test results are supplied, so the stated adaptability and risk control are not demonstrated by performance evidence. The source also lacks an explicit stop-loss rule. The document suggests volatility and volume filters, adaptive settings, and added stops as possible extensions, not validated improvements.

Key ideas

• The momentum module trades crossovers between short- and long-period EMAs.
• The mean-reversion module uses price crossovers back through the outer Bollinger Bands.
• Each module can be enabled or disabled independently.
• The overview says five-minute bars, while published backtest settings specify one-hour bars.
• No performance results are reported, and the source does not define an explicit stop-loss rule.
